INTERCEPTING-CI-IUTE.

To all whom it may concern.'

Be it known that we, WALTER W. DORSEY and JAMES C. DoRsEY, citizens ofthe United States, residing at Las Animas, in the county of Bent, Stateof Colorado, have invented a new and useful Intercepting-Chute, of whichthe following is a speciiication.

This invention relates to intercepting chutes used in taking a samplefrom any portion of a load of beets, potatoes or simi* lar vegetableswhile the same is being unloaded into a freight car for shipment andcontemplates to provide an intercepting ch'ute which will automaticallyintercept a predetermined quantity of vegetables from any desiredportion of the load while the same is in transit over the deliveryscreen to the freight car; to provide an intercepting chute which willautomatically rock back from operative position after the sample istaken from the load so as to permit the discharge of the vegetables overthe delivery screen to continue uninterrupted; to provide anintercepting chute which will not afford lodgment for earth scraped fromthe vegetables during their transit over the screen.

In the shipment of beets, a certain amount of weight must be detractedfrom the total weight of the load to account for earth clinging to thebeets. A dirt apron is usually reversely inclined from the discharge endof the delivery screen to collect the earth gravitating from the screenbut, as is well known, the greater portion of the earth caked upon thebeets rides with them into the car. It is to determine the amount ofthis earth that my present invention is devised and employs for thepurpose an extensible chute suspended by hangers from a track secured tothe under side of the dirt apron and adapted to travel transversely onthe apron to take the predetermined amount of beets from any particularportion of the screen and trip the same into the measuring receptacle.

The preferred form of our invention is illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of our interceptingchute in operative position. Fig. 2 is an enlarged view in elevation ofthe reverse side of the intercepting chute. Fig. 3 is a longitudinalsectional View of our improved chute showing .the same in closed po-Specicaton of Letters Patent.

sition. Fig. 4 is a longitudinal sectional view through our improvedchute showing the same in open position.

Referring to the parts by their reference characters, 4 designates thebeet screen and 5 the dirt apron. Secured transversely the bottom faceof the dirt apron is a pair of tracks 6 upon which travel the hangers 7that support the intercepting chute. The intercepting chute consists ofa supporting frame comprising side bars 8 connected to gether adjacenteach end by cross braces- 9. J ournaled in the side bars 8 are theextremities of a pair of U-shaped rocker frames 10 and 11 which supportupon their intermediate portions a sectional chute. The lower sectionofthe sectional chute comprises side walls 12 and a bottom wall 13 whichcon nects the Yside walls adjacent the delivery end of the chute. Theside walls are extended in their planes to form arms 14 remote from thedelivery end of the section to receive the upper section. The uppersection of the sectional chute comprises side walls 15, a bottom wall16, and an inclined end wall 17. Eyes 18 pivotally secure the rockerframe 11 to the bottom wall of the upper section. The side walls of theupper section slidingly fit the arms of the lower section and arepivotally connected thereto by pivot bolts Or like connectors 19. Theupper section is thus pivoted at one end to the lower sec tion and maybe rockedout between the arms 14 of the latter, this pivotal movementbeing limited by the rocker frame 11.

A pair of rocker links 20 connect the free ends of the arms 14 of thelower section with the side bars 8 of the supporting frame. The linksare less in length than the wings of the rocker frame 11 and as thechute is rocked the arc described by the rocker frame is greater thanthat described by the links so that the upper section is expanded fromthe arms 14 as the chute is rocked upward and retracted as the chute isrocked to its normal position. A greater intake throat is thus presentedto the beets advancing down the beet screen than is obtainable with anordinary chute. Secured to the side bars 8 of the supporting frame arehangers 21, the extremities of which project beyond the bottom of thesectional chute and are provided with suitable bearings to receive acrank shaft 22. A link 23 is pivotally connected at one end to the crossbar of the rockerframe 11 and is provided at its opposite extremity witha suitable Y bearing to receive the crank 24 ofthe crank shaft. Formedintegral with one extremity of the crank shaft is a crank 25 upon theextremity of which is swiveled a lilik 26 that carries on its freeextremity a weight 27.' The weight 27 is sufficient to counterbalancethe weight of the sectional chute and normally holds the latter inoperative or expanded position, as best seen in F ig.' 1.

Projecting downwardly from the cross brace 9 is a leaf 28 which extendsnearly to rthe bottom walls 16 of the upper section f and defines acompartment adjacent the infl'take end of the latter. "entirely acrossthe sectional chute and is "provided adjacent its secured end with a Theleaf 28 extends vlooped portion 29. A trap door is pivfotally secured atone end to the side bars )of the supporting frame and operates when inclosed position to formfa closed recep- Lvtacle in the intake end of theupper section. `vThe'hinged end of the trap door 30 bears against theopposed face of the loop 29 ,throughout its entire length, theparticular advantage of this construction being that the n hinge is heldagainst any tendency to buckle during severe service. A link 31 ispivotally connected at one end to a cross b race32 car- Hried by thelower section rand ispivotally connected at its opposite end to theVfree extremity of the trap door. The link 31 be- .',ing secured at oneend to the transverse brace 32 of the lower section will be carried withthe latter in its movement and will operate to swing the trap door intoclosed for open position as the chute is rocked lto operative orreleased position.

f In order to prevent earth from gravitatfing from the free end 32 ofthe screen into the intercepting chute, a plate 33 is secured A to thebottom face of the screen, as shown. lVhen in released position theinclined end 1 face 17 of the upper section is so positioned screen thatearth gravitating therefrom'willV relatively to the discharge end of thebeet sftrike'the said inclined face and be directed Aoutwardly from thechute. f

I In operation the chute is advanced along the track 7 with the partspositioned as shown in Fig. 4c until the portion of the beet sol i V11Ato advance the intake throat of the sectional chute above the deliveryend of the beetvscreen. The sectional chute is expanded crassa isgradually overcome until finally the total` weight of the accumulatedbeets overbalances the weight 27 and the trap door is sprung. The weightmay now be caught and held from gravitating so that the beets `containedin the chute may be discharged.

A hopper 33 is secured to the discharge end of the chute and a measuringbasket or other container 34 is detachably secured to the spout of thehopper to receive the beets therefrom. The beets contained in themeasuring basket may now be freed from the earth caked upon them andthis earth measured to obtain the weight of earth clinging to themeasured quantity of beets. A number of samples may be taken fromdifferent portions of the load of beets being discharged over thedelivery screen and from the total weight of the earth removed from theentire measured quantity of beets a basis for calculation is obtainedfrom which the total amount of earth contained in the loaded car may beestimated.

From the foregoing description, taken in connection with theaccompanying drawing, it is thought that the construction and operationof our invention will be easily understood without a more extendedexplanation, it being understood that various changes may be made in theform, proportion and minor details of construction without sacricing anyof the advantages or departing from the spirit of the invention.
